You can disable this with `--no-auto-compact`.

Alternatively, you can set `--threshold=100` to never consider partially unused data, but only delete full volumes. This will prevent download of `dblock` files, except for small files.

The options `--small-file-size` and `--small-file-max-count` can be used to further control when Duplicati will download small files and merge them into a large volume.
